Taiwan's advanced power supply design company Huajing Technology recently introduced a powerless LED driver with no electrolytic capacitors, no inductance, and no transformer conversion. It completely solves the problems of power supply due to the life of electrolytic capacitors, transformer volume and low drive efficiency.
The traditional LED lighting design is basically divided into two parts, namely the LED lamp part and the power module part. In the LED lamp segment, due to the rapid expansion of production scale, the cost is rapidly reduced, and the lighting cost per unit is gradually balanced with traditional lighting. The power module part alone is limited by the traditional AC to DC hardware architecture, and the cost does not change significantly.
In order to solve the cost dilemma of the power supply part, Huajing Technology introduced the LED Driver IC --- DR3062 which directly uses AC power. Because you don't have to pay more attention to DC, you don't have to use a relatively large transformer, which saves a lot of space. Of course, it is no longer necessary to use electrolytic capacitors that are not resistant to long-term use, which greatly improves the reliability of the products, so that the LED lighting can truly achieve the longest product life allowed by the LED lamp particles, and is not limited by the short life cycle of the electrolytic capacitors. This is exactly what LED lighting should promise to the planet: environmental protection, green energy, and long-term efficiency.
The DR3062 has a total input power of approximately 7W and can drive 72 general (Vf approximately 3.0V) lamp pellets with a brightness greater than approximately 550 lumens. Divided into TSSOP14 and SOP8 packages. According to the different photoelectric characteristics of the lamp, customers can also configure different numbers of lamp and grain combinations. Birch also provides related software tools to facilitate the necessary minor modifications.
All functions have been integrated into a single chip, and the number of external components has been greatly reduced. The design of the luminaires has become very easy, so that manufacturers who are interested in promoting LED lighting can start producing their own brands of lamps almost as long as they can obtain the lamp housing. This concept, in fact, is identical to the concept of MediaTek mobile phone single chip, that is: customers only need to pay attention to assembly and marketing channels, all technical problems will let Huajing help customers solve.
Customers may have doubts: Is such a low-cost product reliable in terms of security protection?
The DR3062 has also considered these problems for customers. The chip has designed corresponding protective measures under special conditions such as static electricity, overvoltage, lightning strike, and surge.
The accumulation of real experience in the product really takes a considerable amount of time. In fact, based on conservative principles, the DR3062 has been field tested for use by a handful of birch crystal partners for nearly a year. The overall result is satisfactory. After receiving considerable positive feedback from these customers, Huajing began to promote all LED lighting related customers. Shenzhen Ruiyuanguang Technology Co., Ltd. is an agent of Huajing, officially accepting customer sample applications.
